Sash-cord fastener



Patented Apr. 7, 1931 UNITED STATES PASQUALE FRIGIOLA,

SASH-COBD Application filed June 22,

My invention relates to means for attaching weight cords to window sashes, and has for its object to provide simple and effective means by which the weight cord when broken or worn may be renewed and attached to the sash without removing the sash from the Window frame.

To this end my invention consists primarily of a metalliccord coupling member permanently attached to the window sash on each side, a corresponding cord coupling member to which the cord is attached and which can be inserted between the sash edge and the frame into engagement with the 1 sash coupling member, and means whereby the cord can be conveniently fastened to the cord coupling member and the cord coupling member conveniently locked in engagement with the sash coupling member.

My invention also comprises means for gaining access to the sash weight box in the window frame for attaching the new cord to the weight.

In order that my invention may be fully understood, I shall first describe in detail the mode in which I at present prefer to carry this invention into practice.

Reference is to be had to the accompanying drawings forming part of this application for patent, in which like parts are designated by the same numbers in all the figures.

Figure 1 is a front sectional elevation showing means for gaining access to the sash weight box, in accord with my invention.

Figure 2 is a front sectional elevation showing the sash cord and sash coupling members locked together in accord with my invention.

Figure 3 is a sectional side elevation of the same on the line 3-3, Figure 2.

Figure 4 is a detail view of the sash coupling member detached.

Figure 5 is a detail view of the sash cord coupling member detached; and Fig. 6 is a sectional view on the line 6-6, of Fig. 3.

In the specific embodiment of my invention shown in the drawings, 6 designates the window frame, 7 the window sash, 8

strip, 9the sash weight and 10 the sash cord. To gain access to the sash weight, without removing the window stops and sash, I prefer to make the lower section of the parting strip 12, separable from the upper section thereof, so that when the sashes areraised, the said lower section can be separated from the upper section as shown in Figure 1, and the weight covering box or strip 8, detached for fastening the new cord to the weight, the cord having been previously passed over the pulley and down into the weight box in the usual way. a

For attaching the other end of the cord to the sash, Ipreviously secure in a groove in the edge of the sash a sash coupling member 13, consisting in its present form of an angle iron 14:, the flat upper horizontal arm of which is offset medially at 15, and is secured as by screws in a groove 16 in the upper edge of the sash, and the lower vertical member 17 of which is secured, as by screws, in the groove 18 in the vertical edge of the sash.

To attach the cord 10 to the sash coupling member 13, I prefer to insert the end of the cord in a pliable split sleeve 19, having oppositely out-turned flanges 20, and insert the neck of said sleeve 20 lengthwise in a longitudinal slot 21 formed in the lower end of the cord coupling member 22, so that the opposite sides of the split sleeve will be pressed together and bound tightly around the cord.

The split sleeve 19 is also by preference punched and indented at 23 into the cord additionally to fasten the cord therein.

The cord coupling member 22 has, in this example, a flat vertical arm to which the split sleeve 19 and cord are attached as described, and which carries a headed guide stud 24. The stud 24 is adapted to enter an aperture 25 at the end of a longitudinal slot 26 in the sash coupling member 17, and slide lengthwise in said slot, until a stop stud 27 enters the end aperture 25.

i The cord coupling member 22 has also an upper horizontal arm 28, which fits in the outer offset portion of the corresponding arm of the sash coupling member 13 V and is securedthereto by a screw 29.

The stop, stud 27 is thus secured in the end aperture 25 and securely locks the cordv coupling member 22 against lengthwise movement on the sash coupling member and sash.

The cord is thus securely attached to the sash, but can be easily detached therefrom and renewed without removing the sash as previously described, by simply" unscrewing the screw 29, and sliding the cord coupling member 22 upward and out of engagement with the sash coupling member 13.

- In the case of a sash chain being used instead of a cord cable, a hook; or. eye is formed on the lower end of the chain or cable coupling member22, to becaught. by alink of the chain. g It is evident that'manyvariationsmay be made in the specific performance of myinvention without departing, from the boundaries of the following claims.

I- claim? as my invention:

1. ,A sash cord fastener comprising a sash coupling member having a longitudinal slot at. its lower end, a split sleeve to receive the cord having out-turned flanges tofenter the slot and be compressed thereby to bind the cordin the split sleeve, and meansfor securing; the sash coupling member and cord coupling member together, so that the form- Q er engages the out-turned. flanges to hold them against withdrawal;

2.. A sash cord fastener-comprising a sash coupling member, a cord coupling member having alongitudinal slot with a flaring end, a split sleeve to. receive the cord hav ing out-turned flanges to enter the slot, and he compressed: thereby to bind the cord in the split sleeve, and means for securing the sash coupling member and'the-cord coupling member together, whereby the out-turned flanges are prevented from being drawn out of the slot. 7 I

3. A sash cord fastener comprising a sash coupling member, a cord coupling member adapted to slide lengthwise on the sash coupling member and having a longitudinal slot in its lower'end, and a split sleeve to receive the cord having outturned' flanges to enter the slot and be compressed thereby tobind the cord in the split sleeve.
